Application of Genetic Algorithms and Data Mining in Noise-based Testing of Concurrent Software
Šimková, Hana ; Kofroň, Jan (oponent) ; Lourenco, Joao (oponent) ; Vojnar, Tomáš (vedoucí práce)
This thesis proposes an improvement of the efficiency of testing concurrent software by employing data mining techniques and genetic algorithms in the process of testing concurrent software. Concurrent, or multi-threaded, programming has become very popular over the last few years. However, as the concurrent programming is far more demanding the sequential programming, its increased use leads to a significant increase in the number of errors that appear in commercial software due to errors in synchronization. Finding such errors using traditional testing methods is difficult. Moreover, repeated test executions of traditional testing that are performed in the same environment will typically examine similar interleavings only. Hence, the noise-based injection approach is used for influencing the scheduling by injecting various kinds of noise (delays, context switches, and so on) into the common thread behaviour which stress the software and can to show some rare behaviour. However, for the noise injection to be efficient, one has to choose suitable noise injection heuristics from among the many existing ones as well as to suitably choose values of their various parameters, which is not easy. In this work, there are used data mining methods and genetic algorithms and their combinations to deal with the problem of choosing such noise injection heuristics and values of their parameters. Besides setting up of the goals of the thesis, this proposal also provides a brief summary of the state of the art in application of data mining techniques and genetic algorithms to program testing problems.

Nástroj pro analýzu obsahu databáze pro účely testování softwaru
Kropáč, František ; Šimková, Hana (oponent) ; Smrčka, Aleš (vedoucí práce)
Akceptační testování aplikací před produkcí zahrnuje testování reálně vypadajících scénářů při používání aplikace. Tvorba testovacích dat pro aplikace využívající databázový systém je komplikovaná z důvodů specifikace omezení dat, která spadají do domény testované aplikace, a specifikace strukturálních omezení resp. vztahů mezi těmito daty. Tato práce se zabývá problematikou detekce datových vazeb v již existující relační databázi. Výsledkem je nástroj, který automaticky řídí a zprostředkovává detekci omezení v datech relační databáze. Výstupem detekce je váhově ohodnocené omezení dat, které reprezentují jak datový typ, tak vazbu mezi tabulkami a sloupci relační databáze. Tento výstup je pak možné použít pro generování náhodných testovacích dat, které budou reprezentovat vstupy pro reálně vypadající scénáře použití testované aplikace.

Automatizace procesů agilního vývoje
Jašek, Tibor ; Smrčka, Aleš (oponent) ; Šimková, Hana (vedoucí práce)
Cieľom diplomovej práce "Automatizace procesů agilního vývoje" je štúdium agilných metodík so zameraním sa na vývoj v spoločnosti Kentico. Práca popisuje rôzne nástroje na podporu agilného vývoja software vrátane nástrojov JIRA Software a Confluence, ktoré sú používané v spoločnosti Kentico. Podstatnou časťou je analýza súčasných procesov v spoločnosti a návrh optimalizácie a automatizácie ich riešenia. V rámci implementačnej časti je realizovaná webová aplikácia, ktorá vizualizuje metriky vyplývajúce z analýzy a návrhu optimalizácií. Súčasťou práce je tiež zhodnotenie jej realizácie a diskusia o možných vylepšeniach.

Automatic Template Pattern Recognition
Kovařík, David ; Lengál, Ondřej (oponent) ; Šimková, Hana (vedoucí práce)
Spam does not occur as separate messages, but it is sent in so-called campaigns. They are usually generated by a certain template which allows producing large amount of semantically, but not syntactically, equivalent messages. The goal of this work is to design an algorithm able to reversely extract a template of a campaign from a set of concrete messages. The main focus is on spam in SMS communication. However, proposed method is general enough for wider use. The proposed algorithm is based on a method of aligning to sequences, which is used in bioinformatics to detect similar regions of protein strings. Resulting templates are represented as regular expressions. The tool is able to visualize extracted templates using HTML.Results of the tool were validated on more than three hundred real-world campaigns. In most cases extracted regular expressions were able to identify their source campaign.

Automatické regresní testy pro SW balíčky SDK a CMSIS
Svoboda, Tomáš ; Šimková, Hana (oponent) ; Crha, Adam (vedoucí práce)
Tato bakalářská práce se zabývá návrhem a popisem implementace automatických regresních testů pro softwarové balíčky SDK a CMSIS s využitím systému pro kontinuální integraci Atlassian Bamboo. Cílem bylo vytvořit sadu testů nad vývojovým prostředím MCUXpresso, IAR Workbench a uVision. Dále vytvořit sadu testů pro porovnávání souborových struktur a souborů mezi novými a předešlými verzemi softwarových balíčků. Podstatnou částí této práce je teoretický základ týkající se algoritmu a porovnávání strukturovaných souborů XML a jeho modifikací. Pro vizualizaci výsledků regresních testů, kvůli velkému objemu dat, bylo potřeba vytvořit přehledné výstupní rozhraní.

Remote Deployment of InfiSpector
Číž, Marek ; Šimková, Hana (oponent) ; Lengál, Ondřej (vedoucí práce)
The InfiSpector is an application that provides graphical representation of JGroups communication happening between nodes in an Infinispan cluster. We want to separate InfiSpector application from its infrastructure and let users spend time by focusing on using InfiSpector, making conclusions from data provided by InfiSpector, not setting up its working infrastructure. In order to make use and access to InfiSpector easier and quicker, we want to deploy InfiSpector to a cloud service. Cloud service is Internet-based computing that allows users to share computing resources (e.g. servers, storage, applications and services) and data through the Internet. Cloud is also easy to access. As a cloud service was chosen Openshift. Openshift has many tools for easy development, quick deployment, and many tools for running an application. It also allows to have a free user account for everybody.\newline There is also description of how to configure back-end of the InfiSpector in this thesis. Next step is Openshift description, including its overview and configuration files necessary for InfiSpector deployment, development, and running.

Unified Reporting for Performance Testing
Kůrová, Martina ; Vojnar, Tomáš (oponent) ; Šimková, Hana (vedoucí práce)
Modern advances in software technologies for today’s application development have allowed for developers to concentrate less on issues, such as performance and resource management, and instead spend more time on developing the application functionality such that the time to market is reduced. Consequently, performance analysis and optimization become more difficult and create a need for advanced performance tools that should provide a clear report of the application in terms of its performance and allow a fast interpretation of these results. This work investigates typical performance problems of today’s applications and offers approaches on how to automatically detect them. Using statistical methods like regression and correlation analysis, investigation of measured values is performed in order to detect performance deviations that possibly occurred in an application under test. The proposed approach has been implemented as a new Reporter component into an open source performance testing tool PerfCake, developed by QE engineers from Red Hat Czech s.r.o. The developed component is capable of detecting and reporting possible issues and their probability. A unified report from all pre-specified measurements is created in such a way that all detected performance issues are immediately visible. The aim is to improve an end-user experience and usability when reading the report from performance testing.
